application filed December 30, 1926. Serial No; 157,958.

This invention relates generallyto washing machines ofthe type having a vertical tub provided with meansufor agitatlng the water and the clothes therein, and has pan ticular reference to a lid or cover to be applied directly tothe top ofthc tub for closing the same. i r i The aim of the present invention is to provide an improved cover for washing machinetubs, which will effectively prevent water and suds from, being thrown, splashed or carried out of the tub by the agitating or circulating means or by .the gases and vapors generated within the tub; which will 5 permit the gascsandvapors to escape from the tub, thereby relieving presstnfe therein without in any way affecting or displacing the cover; which may be readily positioned in place on and removed from the tub;

manufacture and light, in weight; and which may be easily and thoroughly cleaned.

Other objects will in part be obvious and in part pointed out hereinafter more in detail.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawing, wherein I have shown for illustrative purposes, one of the many embodiments which the present invention will take:

Figure l is a sectional view taken centrally and vertically through my improved cover and diagrammatically illustrates a. washing machine tub to which the cover may be applied; and

Fig. 2 is an elevational view looking at the bottom of the cover.

As an instance of a use tov which my improved cover may be applied, reference may be had to a washing machine having a tub mounted for oscillation about a vertical axis, the tub having a fin for circulating or agitating the water, but it is to be understood that my invention is not limited to a tub of this specific type. In the accompanying drawings, I have shown such a tub, the tub being designated with the letter A and the fin by the letter B. By preference, the upper end of the tub has a flange C, the edge which isneat in appearance, economical in of which forms a. seat for any improved air, etc. ,In the present illustrative dis closure of the invention, the cover shown as being formed of two sheet metal members 10 and 11 spaced apart by arim or flange 12 so as to provide a chamber 13. The sheet metal member 10, which constitutes .the upper wall of the chamber 13, is gem orally of convexo-concave or dome shape: 1

and is provided at its edge with a generally fiat ring-like portion 14., The lower sheet of metal 11, which constitutes the bottom wall of the chamber 13, is shaped generally similar to the member 10, but' the dome shaped portion of the lower member maybe of somewhat larger radius than the upper sheet so that the chamber gradually increases in height toward the center of the cover, The lower sheethas a generally flat ring-like portion 15 corresponding generally to the portion 14-. For the purpose of spacing the members 10 and 11, one of them, in the present instance the member 11, may have a flange or rim 12 which is slightly tapered so as to have a wedging lit in the opening in the top of the tub. The two members of the cover are united by a seam 16. 17, 17 designate handles. The upper wall of the chamber is provided with a centrally located vent or air hole 18, and the lower wall has, in the ring-like portion 15, a plurality of angularly spaced vents or air holes 19.

With the arrangement described, when positioning the cover in the opening in the top of the tub, it is not necessary to force the cover to its seat and against the pressure within the tub because thepressure is re lieved through the chamber and vents. hen the cover is in place, the gases, vapors and the like may escape from the tub by passing through the ports 19, the chamber 13 and out through the vent hole 18 without any danger of the water or suds being carried out by these gases or vapors. 1n fact, after inserting the flange 0r rim in the top of the tub, the cover will automatically seat itself, so to speak, and will hold itself in position.

means should throw, water and suds through the ports 19, the water and suds would not pass out through the air hole or port 18, but, on the other hand, they would be caught within the chamber 13 and flow back into the tub through the ports 19. My improved cover may be very easily cleaned, it being merely necessary to pour into the hole 18 a cleaning fluid which will drain from the cover due to the shape of the walls of the chamber,

As many changes could be made in the above construction and many apparently widely diiferent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that-the .language used in the following claims is intended to cover all of the generic and spe cific features of the invention herein described and all statements of the scope of In the event that the escaping air or vapors should carry, or the agitating the invention which, as a matter of language, might be said to fall therebetween.

I claim as my invention:

1. A cover for washing machine tubs having a chamber provided with a convex lower wall and a concave upper wall, said lower wall having adjacent its edge a plurality of air holes'and said upper wall having venting means at the highest point of the chamber.

2. A cover for washing machine tubs having a chamber provided with a convex lower wall and a concave upper wall, said chamber gradually increasing in height toward the center of said cover, said lower wall having adjacent its edge aplurality of air holes and said upper walls having a centrally located air hole.

3. A cover for washing machine tubs comprising a pair of sheet metal members, one of said members having a tapered flange and'the other of said members having its edge joined to said flange, each of said members being generally dome shaped and having a fiat ring-like edge portion, the lower of said members having in its ring-like portion a plurality of air holes and the upper of said members having a centrally located air hole.
